ADDING-MACHINE.

Application filed March 18, 1905. Serial No. 250,842.

To all whom may concern:

Be it known that I, Jnssn G. VINCENT, a citizen of the United States, residing at Detroit, lVayne county, Michigan, have-inmonly designated'as adding or calculating machines of the type adapted to print, list and add or accumulate individual items and also to print a total or footing of such items at the will of the operator, which "type of machine is exemplified by the well known Burroughs adding machine as substantially illustrated and described in United States Letters Patent Nos. 504,963 and 505,07 8, issued on September 12, 1893, for the inventions of William S. Burroughs.

The object of my invention is to provide novel, simple and efiicicnt mechanism for indicating to the operator' by a visual indicator or signal or otherwise the fact whether the machine is clear, that is, set at zero position, or whether an item or amount remains in the machine,-(thereby rendering the machine in non-clear condition) with the result that the operator, when about to begin a new list ofitems, may tell at a glance whether the machine is in condition to re- To this end, and as hereinafter more specifically described, I

7 provide 6. g. a visual signal upon the keyboard and put the same under the control of the clearing mechanism of the machine by means of such connections that whenever the clearing mechanism is operated the signal which has thertofore been moved or shifted from clear to nonclear condition or indication shall thereby be restored to clear position, it being understood that the signal is changed to non-' clear position upon the operation of the machine for the first item and remains in such ff non-clear position for all subsequent items and in fact so long as any item or 1 amount remains in the machine and until the machine is cleared.

For the sake of affording a clear understanding of my invention, I have chosen to describe and illustrate'it in connection with the well known Burroughs adding machine, in which my invention may be incorporated as an improvement or attachment without alteration of the old parts thereof. However, it will be understood that my invention is not to be limited, inits application, to this particular type of machine, but that it may he applied and used in connection with other machines of the same general type and used for the same general purposes.

In the drawings, Figure 1 is a sectional elevation of a Burroughs adding machine, the'section being taken just inside of one of the side frames and illustrating the lefthand side of such machine with my invention embodied therein; Figs. 2 and 3 full sized views of certain of the parts of the Burroughs machine together with the parts of my improvements and illustrating different relative positions thereof; Fig. 4 a

plan view of the signal proper and a part of the keyboard; Fig. 5 a perspective of the signal proper; Fig. 6 detail Views of the means for operating the arm 1216; Fig. 7 a sectionof a part of the keyboard. illustrating a'modifiedforn of signal; Fig. 8 a plan view of such modified signal; and Fig. 9 an elevation of modified construction of the signal controlling mechanism.

Inasmuch as the Burroughs machine is well known as to its general construction and modeof operation, only those parts thereof which are more or less directly concerned with the operation of my signal and its connections need be described.

As is well known, the keyboard of the Burroughs adding machine is provided with a series of keys 291 arranged in rows of differentdenominations, increasing from right to left, and each row having keys representing the digits 1 to 9, in addition to which such keyboard is provided as shown, with a total key or button 265 which, whenever depressed, controls the action of the clearing and totaling mechanism. \Vhen the total key or button is depressed and kept depressed throughout the full stroke of the operating handlethat is, during one complete operation of the machine, a grand total is taken, but in case such total key or button is kept depressed only during the forward movement of the operating handle, only a sub-total is taken or imprinted upon the paper on the laten. Consequently, when a grand total is taken the machine is cleared, but when only a sub-total is taken the ma chine is not cleared, but the amount of the Specification of Letters Patent. Patented J an. 31 1911.

sub-total remains in the machine as an amount to which the subsequent items are still to be added. As is well known, whenever the operating handle is pulled forward (the total key not being operated) the pinion frames 910 which carry the adding 1 The rocking arm 813 which in the forward movement of the operating handle moves in an anti-clockwise position (Figs. 1, 2 and 3) is provided at its upper end with a wipe plate or block 821, which is spring pressed by means of the spring 883. This wipe plate is arranged to actuate a three-arm p ate 913 which is mounted u on the shaft 911 and provided upon two 0 its arms with studs or pins marked 961 and 961". The other arm 913 is pivotally connected to the rearward end of the pitman 914. -Upon'thc first or rearward movement of the rocking arm 813, the wipe plate 821, by its engagement with the in or stud 961, moves or swings the rocking plate 913 andconsequently its arm .-)13 in an anti-clockwise direction, with the result that the pinion frame 910 and adding wheels mounted therein are rocked forwardly to the right in Figs. 1, 2 and 3, by reason of its connection with the rocking plate 913, through the medium of the pitman 914. The sector bar 611 (Fig. 1) as well as the sector 610 corresponding to the row of any 0 rated or set key or keys will descend a distance corresponding to the value of the particular key or keys so operated but without. affecting the adding wheels which have been rocked out of engagement with the sectors, as just described. Upon the return movement of the rocking arm 813, its wipe plate 821 will engage the stud 961 and restore the rocking plate 913 as well as the pinion frame 910 and the adding wheels and inions carried thereby to the normal position illustrated in Fig. 1, so that such adding wheel pinions will be brought into mesh or engagement with the Sectors 610 so that after the item has been printed and as the operating handle is on its return stroke, the amount or value of any depressed key is transferred from its sector bar to its corresponding inion and adding wheel in the upward an restoring movement of such sector bar or bars. \Vhen, however, a grand total is to be taken the operatordepresses the total key or button which by reason of its connection with the pitman 914. through the medium of the long vertical link 911 (spring pressed by a spring 983) and the arm 22? opcratively connected with the upper end of such link, the bifurcated end 0 the pitman 914 is depressed to the position indicated in Fig. 3, with the result that when the arm 813 is rocked to the left and the pitman 91% thereby shifted to the right, Fig. 1, the )inion frame 910 is not moved by reason 0 the change'in position of the pitman 914-, and consequently the adding wheels remain in operative relation with their sectors (310. Upon further operation of the machine, the amounts on the adding wheels will be transferred to the sectors (310 which will be allowed to descend a distance corresponding in value to its corresionding adding wheels After the total has een printed in the well known manner, the rocking arm 813 by engagcment with the stud 901 moves the pitman 914 rearwardly or to the left in Fig. l,

with the result that the pinion frame 910 is rocked forwardly so as to remove its adding wheel pinions out of engagement with the sectors 610, whereupon said sectors are returned to normal position without disturb ing or moving the adding wheel pinions which, in this operation of taking the total, have all been turned to clear or zero position. Afterthe sectois 610 are restored to normal position, the pinion frame 910 and its adding wheel pinions are rocked rearwardly to normal position with the adding wheel pinions in engagement with their sectors. The operation just described is that for taking a grand total but when it is desired to take sin] ly a sub-total the total key is not kept epressed during one entire cycle of operation of the machine or complete stroke of the handle, but is released at the end of the forward movementof the operating handle, with the result that the adding wheel pinions are permitted to remain in mesh with their sectors (310 during the upward or restoring movement of the latter, whereupon the amounts or values which were transferred from the adding wheels to the sectors have now been transferred back to the adding wheels after such amount. which is the sub-total, has been imprinted upon the paper on the platen.

In a Burroughs machine each row of keys is provided with a plate 214 adapted to slide to the left upon the depression of any one of the keys in its row. One result of this sliding movement of the plate is to rock a bail for the purpose of locking the total key in normal position and prevent the depressing of such total key when any one or more. of the keys on the keyboard is set. As herein shown, each bar 214 is provided with a depending lug 214 which, when such bar is slid, as explained, moves a universal barAOQJ; to the left. this bar forming a part of the bail comprising also two side arms 4241 which are mounted to swing upon the shaft 4001. When the bail is thus swung to the left-,- its upper end is brought into the path of movement of the projection 261% on the arm or key stem 227 so that the total key is locked in upward position. i

, The parts above described are those which are well known in the Burroughs machine and comprise the parts which are more directly concerned with the construction and operation of my clear signal device, which will now be explained.

Upon the shaft or stud 1400, I swing or pivot a long Vertical arm 1210 which will hereinafter be termed the signal arm, the upper end thereof being operatively con nected with the signal proper by suitable connections. proper comprises a curved plate or partial drum'1215 having at one portion thereof the word C-L-E-A-R and another portion by preference colored red to indicate danger or non-clear position Fig. 5.

This signal is arranged within a case- 12H.

having a sight opening so as to expose the indications made by the signal in its differentpositions. At opposite ends the signal has radial arms 1215. and through these arms is passed in a pin 1253 whose ends, projecting beyond said arms form the axis or t-runnions for the signal, Figs. 4 and 5. One of these arms 1215 is extended and is pivotally connected to one end of a link 1212, whose other end is connected with the upper end of the signal arm 1210 with the resultthat the movements of such signal arm are communicated to the signal and the latter thereby rocked correspondingly from one position to another in the above operations of the machine, as hereinafter explained. It will be understood that the case 1214 is mounted upon and secured to the upper keyboard plate 213 in suitable manner and also that a slot or opening is provided in such upper plate to permit the extended arm 1215 to pass through. The upper end of the signal arm passes tlu'ough a slot 212" (Fig. 4) in the lower keyboard plate 212 and the operating connection or link 1212 therefore operated in the space between the two keyboard plates, Figs. 1, 2 and 3. The signal, which, in the presentinstance, is placed near the lower left-hand corner of the keyboard adjacent the total key, is thus within the Vision of theoperator as he stands before the machine ready to operate it.

The signal arm is under the control of three parts which I will term interferences, the first interference being directly under the control of the key mechanism and beingoperated only when any one of the keys is set. The second interference is under the control of the parts connected with the dash pot in such manner that it cannot be removed from the path of the signal arm until As herein shown, the signal the machine has been operated far enough to actually get an amount into the machiw The third interference is directly under the control of the total key and its connections, or in other'words, under the direct control of the clearing mechanism, and is for the purpose of changing the position .of the signal arm from non-clear to clear position.

As herein shown, the first interference comprises a latch 1211 which is pivoted upon a shaft or stud 253 and projects rearwardly in such manner that its shoulder 1211 formed on its under edge and near its outer or free end, is adapted to engage a small pin or stud 1250 extending laterally from the signal arm 1210. This latch is normally held downwardly as to its outer or free-end with a yielding pressure, as by means of the coiledspring 1281 fastened at one end to the 7.

clearly indicated in Figs. 1, 2 and 3. As above stated, tl1is latch is under the direct con trol of any one of the keys and to this end advantage is taken of movement of the bail which serves to lock the total key. In the present instance, I provide the side arm 424 of this bail with a stud 1259, which is adapted to engage and cooperate with a cam sur face on the lower edge of the latch 1211 at a point intermediate its length (Figs. 1, 2

and 3). When this bail is in normal posi- I 5 tion, that is when none ofthe keys is depressed or set, the latch is, in normal posi tion engaging the signal arm and holding it to normal-or clear 'position, as seen in Fig. 1. When, however, an item or amount is set up on the keyboard and one or more keys thereby depressed the bail is rocked to the left with the result that the stud 1250, cooperating with the cam surface on the tension of the spring 1281 and thereby disengage the same from the signal arm. This operation removes the first interference which is the latch 1211, but the signal arm is still restrained by the second interference which will now be described. The second interference comprises, in the present instance, and arm 121G pivoted upon the shaft 904 and directly under the control thereof,

latch, will raise the latch 1211 against the it.

which shaft in turn is under the control of the parts working the dash-pot 892, through the medium of arm 922, link 918-],- and arm 813, Figs. 1, 2 and 3. The arm 1216 is spring-pressed to its normal position by a coiled spring 1283 secured at its lower end end of arm 1216. When, in the restoring to move, this arm would immediately change to the arm 922 and at its upper end to a stud 1260 on the arm 1216. When the machine is in normal position aswellas in clear condition and the signal arm therefor in clear position, the outer end of the arm 1216 is positioned directly in the patlrof a stud 1250* projecting inwardly from signal arm 1210. \Vhen the first interference 1211 is removed by depressing a key, as has already been described, the upper end of the arm 1210 would move rearwardly were it not for the fact that the outer end of the arm 1216 is positioned directly in the path that the stud 1250 would have to travel to allow this movement. It will be seen therefore that the signal arm 1210 cannot change position until the second interference 1216 has been removed from the path of 1250*, which is accomplished in the following manner: v

The arm 1216 is provided with a hub 1232, whose inner end has a clutch 1232 cut thereon, Fig.v 6. Shaft 904 is provided with a. similar clutch 930 adapted to engage the clutch 1232 and move it to the position shown in Fig. 3, when the handle is moved to the extreme; forward position. During a full operation {of the machine the arm 1216 will move upwardly and from in front of stud 1250 at the end of the forward stroke of the handle and immediately return to a position in front of stud 1250 as the handle starts on its rearward stroke, provided no amount or item was placed on the keyboard and latch 1211 was therefore engaging stud 1250, but'if on the other hand, an item had been placed on the keyboard and the first interference (latch 1211) was therefore out of engagement with stud 1250, as soon as the arm 1216 moves from in front of stud 1250' and thereby leaves the signal arm 1210 free to the position shown in dotted lines in Fig. 2 or solid lines in Fig. 3, bringing stud 1250" directly under and in the path of the outer movement of the operating handle, shaft 904 returns to normal position carrying with it arm 022, the spring 1283 is extended, leaving the outer end of arm'1216 above normal position and retained in this upper position by stud 1250, Fig. 3. The lost motion provided for in the clutch member 1232 by making it less than semi-tubular as shown in Fig. 6, permits the necessary independent movement in this operation bet-ween the two clutch members. V

Assuming that an amount has been set up in the machine, the latch 1211 is disengaged from the signal arm and the latter remains restrained in its clear position by reason of the second interference 1216. It is desirable that this second interference (arm 1216) remain in the path of stud 1250 until such time as the amount set up on the keyboard has actually been imprinted upon the paper on the platen, and to acoom lish this result I have taken advantage of tie movement of the shaft 904, which is a regular part of the Burroughs'adding machine, this shaft having a slight clockwise movement at the end of the forward stroke of theoperathave imprinted the amount upon the paper upon the platen. This slight clockwise rotation of shaft 904 is sufiicient to raise arm 1216 and performs this function at just the right moment.

As has already been explained, when an amount has been set up on the keyboard and latch 1211 is therefore out of engagement with stud 1250. the handle being drawn forward to the end of this stroke, shaft 90 1 removes interference 1216 and allows signal arm 1210. or rather the lower end thereof, to move forward or to the right, Figs. 1, 2 and 3. The upper end of the signal arm 1210 will therefore move rea-rwardly or to the left and through the medium of the link 1212 will oscillate partial drum 1215 to expose the portion colored red to indicate non-clear condition. ()n the return stroke of the handle, arm 1216 is retained in an upper position by stud 1250, as has already been explained, but arm 922 will return to normal position, stretching or extending the spring 1283. The arm 1216 will remain in this upper position during subseing handle during or just after the hammers I quent operation of the machine and until such time as the total key is depressed in the manner and with the results hereinbefore described, whereupon the stud 1255 which I have termed the third interferences projecting from the side of the pitman 914, is brought to a position just in advance of the bell-crank shaped lever or late 1213, which is normally held with a yie ding pressure to the position indicated in Figs. 1 and 2, by means of aspring 1282 fastened at its upper end to a stud 1251 on si nal arm 1210 and at its lower end to a stu 1256 on the bell-crank lever 1213. This lever 1213 is pivoted on stud 1252 on the lower end of the signal arm and its lower member or arm is extended forwardly toward the stud 1255.

The relative arrangement of this stud and the bell-crank shaped lever 1213 is such that when the total key is first depressed such stud will bear upon the lower end of hellcrank lever and rock it slightly against the tension of its spring, but just as soon as the operating handle is drawn forward so as to cause a forward movement of the pitman 914, the stud will take its position immediately in front of the bell-crank lever 1213, which during the subsequent and rearward movement of the pitman will act as an abutment or interference between such pitman and the lower end of the signal arm, Fi 3, with the result that such signal arm wi l be moved as to its lower end toward the' left, Figs. 1, 2 and '3, and its stud 1250 moved from under theouter end of arm 1216, thus allowing the arm 1216, or second interference, to be drawn through the medium of spring 1283 to a normal position iufront of the stud 1250". Durin this rearward movement of the lower on of signal arm 1210it will be understood that the up per end is moved forwardly or to the right against the tension of its spring 1280, Whereb partial drum 1215 is rocked. through the medium of link 1212, to the division marked clear to thereby indicate a clear condition of the machine, Figs. 1 and 2.

The ope ation just described is for taking a full or grand total, but when a subtotal is taken. that is, when a total is printed but retained in the machine. to which subsequent items are to be added, the machine remains in a non-clear condition and the signal must therefore not be changed from a non-clear to a clear position. The

operation of takingeither a total or a subtotal is exactly the same on a Burroughs adding machine during the forward stroke of the handle, during which stroke pitman 914 has been brought to the position illustrated in Fig. 3, but at this moment when taking a suit-total the total button 265 is released and allowed to ascend to normal position, carrying with it through the medium of link 911 the 'pitman 914, thereby carrying the third interference 1255 above 'the for ard end of bell-crank lever 1213 'to the position illustrated in Figs. 1 and 2.

This operation also carries the lOWBP'llOOk 914 on pitman 914 above and out of engagement with stud 958 on side plate 910. As the lever starts on its return stroke, thereby moving pitman 914: rearwardly, as hereinbefore described, the plate 910 will not be oscillated because hook 914 rides over and misses pin 958. On this rearward movement pit-man 9H will carry with it the third interference 1255, as in a full total, but as this pitman 914 is in an upper position. as illustrated in Figs. 1 and 2, it will entirely miss the endof the bell-crank lever 1213 and allow this lever as well asthe lower end of 1210 to remain in a forward position, and thereby not disturb thesignal which stands in a non-clear position.

The different positions of the parts con stituting and associated with my clear signal mechanism are clearly indicated in the drawin s. For instance, the normal or clear "position isshown in full. or solid lines in Figs. 1 and 2' and the non-clear position is shown in Fig. 1 in dotted lines.

I Fig. 3 shows the 'relat1ve position 'of the parts upon the depression of the total key while the signal is in non-clear position and justprior to the restoration of the sigthe keys on the keyboard, but such arm remains restrained against the movement by means of the second interference consisting of lever 1216. After a key or keys has been depressed on the keyboard, the first interference (latch 1211) will be in the position shown in dotted lines in Fig. 2. but the signal arm will remain in the position shown in solid lines in said Fig. 2 and. the signal will show clear through the sight opening of the case. it this time the signal arm is rcstrained by the second interference, as the stud 1250 is engaged by the end of the arm 1216 in its position asshown in solid lines in Fig. 2. When, however, the handle is pulled to the end of the forward stroke and arm 81 3 thereby rocked in an anticlockwise direction, drawing with it link 9182,, the shaft. 904 is rocked in a clockwise direction through the medium of link 922, thereby raising the second interference (arm 1216) to the position shown in dotted lines in F 2. This movement of arm 1216 permit-s stu'd1250 to be moved in a forward position by the signal arm 1210, thereby allowing such arm to take the position shown in dotted lines in Fig. 2. This movement of the signal arm 1210 slightly oscillates the partial drum 1215 and allows it to exhibit its red portion through the sight opening as hereinbefore described and thereby indicate non-clear 1 condition of the machine.

In Fig. 3 I have illustrated the relative positions of the parts after depression of the total key and a half movement of the rocking arm 813, at which time the bell-crank lever 1213 is in its position rearwardly of stud 1255, so as to be actuated by the latter in the restoration of the signal arm to normal position and the consequent. restoration of the signal from non-clear to clear position. This restoration of the signal occurs just after the printing of the total.

The type of signal. above described is an oscillating drum or partial drum, but itwill be understood that the signal arm may be connected to different forms ofsignal. For instance, as illustrated in Figs. 7 and 8, such arm may be connected with a sliding plate 1219 by means of a link 1220, such plate being arranged to move back and forth in a slot 213 in the upper keyboard plate. ilxtending longitudinally of this plate are the letters FC-L-E-A-R, separated by spaces which are preferably colored red. This signal or signal plate cooperates with a plate 1218, which is secured to the upperkeyboard {plate 213 over said slottherein and the same is provided with a series of sight openings 1218, which are five in number, with the result that when the signal plate is in normal position the letters of the word clear will be exhibited through said openings, whereas, when the sliding plate is in its other position the red spaces are exhibited through such openings to indicate non-clear position.

By preference, as herein shown and described, the si al is not moved or shifted from one position to the other until the first item is positively in the machine, or until the machine is positively cleared. As will be understood from the foregoing description, the signal is shifted from clear to nonclear after the first item has been printed or recorded, and'is, in fact, positively in the machine, and such signal is not shifted back to clear position until the operation for printing a total is completed or innnediately thereafter, at which time the machine is positively cleared.

Referring to the modified form of signal device, which is illustrated in Fig. 9, two interferences are provided of which the first one is the same in construction and mode of operation as the interference comprising essentially the latch 1211 hereinbefore described, which together with all similar parts, are numbered the same as in the preferred form. Such first interference need not, therefore, be further referred to. The second interference comprises a lever pivoted upona shaft A and having the two arms A A on opposite sides of its pivotal point. The arm A which extends as'to its outer end adjacent to the lower end or portion of the signal arm is provided on its upper edge with two separate shoulders a, a, which are adapted at different times and under different conditions to engage a stud or pin 1210 on the signal arm 1210. In the normal condition of the machine and even after a key has been depressed and until the item or amount so set up on the keyboard has been printed, this second interference remains in its normal position illustrated in Fig. 9, with its shoulder a in engagement with the stud 1210 and preventing movement of the signal arm 1210 even though the latter may have been released as to the first interference.

Assuming that an amount has been set up in the machine, the latch 1211 is disengaged this stud B will rock the arm A upwardly and the other arm A downwardly, thereby removing the shoulder a from engagement with the stud 1210 and permittin the signal arm or rather the lower end t ereof to move to the right or forwardly of the machine a slight distance until stopped and held by the second shoulder a. The signal which had heretofore shown or indicated clear has now been oscillated by reason of its connect-ions with the upper end of the signal arm, to indicate non-clear position, such as the red space formed on the signal. The signal remains in this position for all the subsequent items listed, but when it is desired to take a total, the total key 265 is depressed in the manner and with the result hereinbefore described, with the result that such signal arm will be moved as to its lower end toward the left, Fig. 9, and its stud 1210 moved frome engagement with the shoulder a to such position as to be engaged by the shoulder a, it being understood that the arm A is normally upwardly spring pressed to accomplish the result stated. In the present instance, this arm A is spring pressed by means of the same spring C. which is connected with the signal arm 1210. The means for restoring the signal arm to normal position are thus the same as those heretofore described and corresponding parts are therefore similarly indicated by reference characters.

Fig. 9 illustrates the position of the parts just after any one of the keys on the keyboard has been operated or depressed, with the result that the first interference (latch 1211) has been disengaged fro mthe pin or stud 1250, but at this time, as illustrated in said figure, the second interference, consisting of the lever arm A is still efi'ective,but adapted to be released in the operation of the machine in the manner hereinbefore explained.
